New Front Pads

[applicationcen]

I always thought the breaks on my Jazz were very sharp and bitey.

They said there was 90% wear so I stupidly said yes to having them changed for new front pads.

Now they are really slippery! You really do have to squeeze the break pedal to get a reaction.

The combo of fluffy breaks and the peculiar improvement in cabin noise makes it feel like a completely driving experience.

You should give them time to bed in but:

your description here is a little worrying.  They shouldn't be that bad.

New brake pads may not bed in for a few 100 miles so brakes may be a bit softer for a while,  but be careful to match pads to disc,  there are combinations of disc and pad material that don't work well together - and as for people who fit high performance pads that have to get up to a high temperature before they have any bite (so are no good around town) - the least said the better.

there are abrasive pads (bite into the disc as the name suggests) and adhesive pads (which leave a thin layer of pad on the disc).  Better to stick with OEM pads and discs as the car companies spend lots of time finding suitable combination of material for all situations,  good bite with cold pads,  not too much fade with hot brakes etc. and good wear life.

I once fitted 'Blueprint' discs and pads to a previous Jazz GD (good quality and not cheap) but took them off and replaced with Honda after I had problems with brake judder.

As Culzean says let them bed in , but if you find the perforamnce does not improve take the car back and insist the dealership puts matters right.

It has not improved over say 30 miles. Ill see what they feel like at 100. Might just take it for a blast on the dual carrige way and do some proper slowing down for the roundabouts!

Largely depends how scored your disks are but will definitely take more than 30 miles.

if the discs are scored the old pads would have worn with grooves in them and had good contact area,  putting new (flat faced) pads onto scored discs means the pads only touching on peaks of the grooves and will not have very good contact until new pads have grooves worn into them.  If discs are grooved you can get them skimmed but depending on how many miles the discs have been on the car (can need replacing after 40 / 50K in some instances, depending on driving style) may be better in the long run to fit new discs fairly quickly before faces of pads assume a bad profile, then you will have to replace pads and discs.
